difference between xsl and xsd?

First of all, it's best to understand that the questions like "what is the difference between {0} and {1}?" are logically incorrect. What is the difference between apple and Apple? Please see my past answer:
what is the difference between the class and encapsulation in programming[^].

Now, you should understand that XSL operated on some really existing XML files. It presents the XML data is some other form, and it can do it with data loss, duplication, etc. This is just a way to transform data. Basically, it is used to create a different representation of XML data, typically in a human-readable form (such as HTML), but not always. Please see:
http://en.wikipedia.org/wiki/XSL[^].

In contrast, XSD does not have to do anything with individual XML files. It really defined a whole class of such files, or, in other words, the set of constraints; and each of possible XMLs may or may not be compliant with it. It defined the metadata defining the class of compliant files. In a way, it defined some semantic language based on XML as on a media. Please see:
http://en.wikipedia.org/wiki/XSD[^],
http://en.wikipedia.org/wiki/Metadata[^].

Solution 1

XSD is an XML schema document, defining the structure of your XML. They're nice to have, but not generally necessary to get the job done. XSL is stylesheet language, and what you're probably looking for is an XSLT, which transforms one document into another as specified by the transform file. XSLT is pretty simple once you get the hang of it--Michael Kay's books are great, or start here: http://www.w3schools.com/xsl/xsl_intro.asp

answer's above: xsl changes or manipulates data, xsd defines data's structure

Solution 5

Xsl - is used to tranform the xml doc.i.e Adding new nodes and Removing new nodes etc..

xsd - is used to validate xml document.Like datatype, range validation
